Abstract
Starting from the case report of photosensitivity epilepsy, PSE when audience were watching on a TV program that broadcast high contrast blue red blinking, a large number of studies about photosensitivity were done leads to regulation for broadcasting system. As a result, high contrast blue red blinking stimulation has the frequency of about 10 Hz that elicit PSE and photo-paroxysmal response, PPR was confirmed and inhibited to broadcast more than 2 seconds. On the other hand, the frequency of the alpha waves exists in this same band, which gives the effect of relaxation. This study analyzed EEG behavior was evoked by blinking stimulation have the frequency was changed from 1 up to 9.5Hz. The experiment result shows the synchronous reaction in 2.5 up to 7Hz, and asynchronous reaction up 7 to 9.5Hz(around 10Hz) in visual cortex and inhibitory cortex reaction in wide area for epilepsy protection.
